Flame Retardant PPE Base Layers

Flame-retardant base layers are technical undergarments worn in direct contact with the skin, designed to resist ignition and minimize the spread of flames. These layers are an integral part of high-performance Personal Protective Equipment (PPE), especially used by professionals exposed to thermal or electrical risks. Unlike ordinary clothing, the fabrics used – such as aramid, modacrylic or blends with treated cotton – remain effective even after several washes. Combined with other flame-retardant garments, they provide effective protection in fire, electric arc or radiant heat scenarios.

Flame retardant base layers offer additional protection in hazardous work environments. Their main benefits include: resistance to fire propagation, thermal insulation, thermal comfort and moisture regulation. These garments help to mitigate burns in the event of exposure to fire or extreme heat, acting as an essential barrier between the skin and the heat source. In addition, the fabrics are breathable and lightweight, promoting comfort during long working hours. At RAG Tailors, we combine advanced textile technology and ergonomic design to ensure protection without compromising the wearer’s daily comfort.

Although the terms are often used interchangeably, there is an important difference: flame-retardant clothing is made from natural or synthetic fibres that are chemically treated or inherently resistant to flames, while flame-retardant clothing generally refers to the treatment applied to the fabric to resist combustion. RAG Tailors’ flame-retardant base layers use technically advanced fabrics that maintain their protective properties even after multiple washes. This ensures long-lasting protection, essential for professionals who are frequently exposed to thermal hazards at work, such as electricians, industrial operators and response teams.

To preserve the properties of flame retardant base layers, it is essential to follow specific care instructions. Wash preferably at temperatures below 60°C, using neutral detergents and avoiding fabric softeners or bleaches, which can compromise the integrity of the fabric. Air drying is recommended, although tumble drying on a low temperature is also permitted for some models. We do not recommend ironing unless indicated by the manufacturer. At RAG Tailors we provide clear maintenance guidelines with each product, ensuring that the user prolongs the effectiveness of their PPE and maintains high standards of safety and durability.

Flame retardant base layers are recommended for any occupational activity involving the risk of exposure to extreme heat, open flames, sparks or electric arcs. They are commonly used in contexts such as the petrochemical industry, power generation, electrical maintenance, welding, firefighting and military or emergency units. In addition to being used as a first layer under protective suits, they provide mobility, breathability and comfort. RAG Tailors provides solutions adapted to the demands of these roles, with certified options that guarantee safety, thermal protection and adaptability to work in extreme environments.

Flame retardant base layers for PPE must comply with European and international safety standards such as EN ISO 11612 (heat and flame protection), EN ISO 11611 (welding protection), EN 61482-2 (electric arc protection) and EN 1149-5 (electrostatic properties). These standards assess factors such as thermal resistance, flame propagation, dimensional stability and durability of the fabric after washing. RAG Tailors products are rigorously manufactured to meet these requirements, ensuring professionals have high levels of confidence and reliability in their personal protection while performing their duties.
